'BENJAMIN S. LAWSON, OF NEW YORK, ASSIGNOR TO AUGUSTUS M. MILLER, OF BROOKLYN, NEW YORK, AND ALFRED GILL, OF ORANGrE, NEW' JERSEY.

Letters Patent No. 94,420, dated August 31, 1869.

IMPROVED SASH-HOLDER.

The Scheduo referred to in these Letters Patent and making part of the Ime.

T o all whom it' may concern had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1, of the drawings, is a perspective view of my invention.

Fignre 2 is a cross-section of same.

Figura 3 is a perspective View of sash with fast-emer.

Figure 4 is a side view, with side plate removed,

and sash-mouldings in section.

` My invention relates to means for holding and operating window-sash; and

It consists mainly in a nove) arrangement of devices intended to serve an efficient purpose in the use named.

`The letter A, of the drawings, represents a section of a window-jamb, and

The letter B, a section of a window-sash, with my device arranged therein.

The letter 0 represents a metallic plate, attached to the side of the sash by screws, adjoining which I form a slot in the face of the sash, as shown, to provide for the adjustment of the elastic wedge a and the roller c, as hereinafter nentioned.

The letter a represent-s a wedge of India rubber, or

other elastic substance, arranged in the, bottom of the slot, as shown. and

The letter c 'epresents a roller, playing loosely in said slot, and arranged to move back and forth therein.

My device operates as follows:

hen the sash is in place, the roller c presses against the rear side of the windowmoulding and as the thin edge of the wedge is placed downward, it allows the window to be raised With ease. W'hen, however, the sash is raised to the desired altitude, the weight of the same falls' upon the roller, pressing it against the partial shoulder formed by the increasing thickness of the we'dge upward, and thereby holding said sash in place.

I usually arrange a roller, c, on each side of the window-sash. i

The above and foregoing description is made applicable to all kinds of sliding frames, and is especially adapted to the windows of carr'ages and railway-cars.

What I claim as my invention, and desire to secure by Letters Patent, is

The window-sash adj uster herein described, having elastic wedge a and roller c, arranged in a slot, as described, substantially as specified.

In testimony that I claim the above, I have hereunto subscribed my name, in the presence of two witnesses.

BENJ. S. LAWSON.
